A continuation of our discussion of John Gottman's research on success in marriage, this time focused on his scientific findings on how friendship operates in close relationships. We start by reviewing the 4 Horsemen of the Apocalypse, throwing in some Nacho Libre and Adventure Time references for good measure. Then we delve into the 3 aspects of friendship: building love maps (something men - and sometimes women - fail to do on dates!), expressing fondness and admiration, and responding to each others' bids for connection.
